Referring first in general to the embodiment of the inventionillustrated in Figs. l through 11, the improved bottle top atomizercomprises a bottle adaptor 10, preferably molded of a synthetic plastic,into the upper end of which is press-fitted a tubular metallic shield orcylindrical sleeve member 12. The shield or sleeve member` 12 isprovided'with a circular side opening 14 for passage of the atomizediluid and has telescopically fitted in its upper end for reciprocal andrelatively rotative motion, a metal cylindrical pump sleeve or shellplunger 16. The upper end of the pump sleeve 16 is topped with a cap 18adapted to be pumped by thumb against the action of an interior spring20 and cause, in the manner hereinbelow to be described, atomized fluidto be discharged from the side opening 14 in the shield 12. The bottleadaptor member 10 may be provided with an internally threaded opening 22at its underside adapting it for screw-on attachment to a bottle B thecontents of which are to be atomized.

Considering now the construction and operation of the improved bottletop atomizer in greater detail, the bottle adaptor member 10 (see Fig.9) which preferably has its outer periphery iluted as indicated by thenumeral 24, is provided with a cylindrical recess 26 in its uppersurface within which the shield 12 is press-fitted. A raised, circularcentral portion 28 is also provided in the adaptor member 10, whichraised portion has a small center bore 30, a small off-center bore 32and a pair of circular recesses 34, 36, ninety degrees mutuallydisplaced. The bores 30 and 32 have respective, radially-extendinggrooves 38, 40 communicating with the annular groove defined by theouter periphery of the central portion 2S and the circular wall of thecylindrical recess 26. A small metallic tube 42 is itted within thecenter bore 30 to provide a nipple on which is attached a flexiblesynthetic plastic tube 44 extending to the bottom of the bottle beingused.

Press-fitted between the inner surface of the shield 12 and the outercylindrical periphery of the central portion 28 of the adaptor member 10is an annular flange or skirt portion 46 of a core member 48. Said coremember has a flat undersurface portion 5i) from which extends a pair oflocating pins 52, S4 tting into the recesses 34, 36 respectively of theadaptor member 10. A vertical bore 56 extends through the core member 48to communicate with the radialgroove 40 (see Fig. 2) and a Vertical bore58 extends through the core member 48 to communicate with the radialgroove 38 (see Fig. 7). The core member 48 has a iirst annular axialportion of reduced diameter 60 forming a first annular shoulder 62 and asecond annular axial portion of further reduced diameter 64 forming asecond annular shoulder 66 (see Fig. 2). The outer periphery of thesecond annular portion of the core member 48 is vertically flattened ata position aligned with the bore 58 as indicated by thereference-numeral 68 to provide an air passage for the purposehereinbelow described. Said second annular portion has a longitudinalrectangular projection 71 at a position diametrically opposite saidflattened portion to provide a locating key for parts hereinbelowdescribed.

The core member 48 is horizontally bored at 72 at a position inalignment with the vertical bore 56 (see Fig. 2), to provide an openingfrom the annular shoulder portion 66 to the interior of 'the coremember. A cylindrical plug member 74 is seated within the centralopening of the core member 48. Said plug member is provided With aninterior right angular channel 76 communieating at one end with the bore72 and covered at the other end by a resilient ap 78 secured at one endin a groove in the plug member 74 and serving as a cheek valve.

Sealing or valve means is provided for shutting off the vertical bores56 and 58 in the core member 48, the same comprising an annular valveassembly 80 of a metallic seal ring 82 (see Fig. 10), within theframework of which a rubber nail 84 is fitted. The real ring 82 isannular in shape and has a peripheral, substantially cylindrical, outerwall 86 and bent over, opposed, arcuate outer top portions 88, 90 joinedat their ends with inner arcuate top portions 92, 94 by interconnectiing portion 96, 98. The interconnecting portion 96 is inwardly steppedin the vertical direction and centrally drilled to provide an opening100. The interconnecting portion 98 is inwardly stepped in thehorizontal direction to provide a rectangular slot 102. The bottom ofthe seal ring 82 is open to allow fitting therein of the rubber sealmember 84, said seal being of such shape and configuration as to iitwithin the seal ring 82 so that its upper and lower surfaces aresubstantially flush with the upper and lower ends of the seal ring (seeFigs. 4 and The seal member 84 is further provided with a verticalopening 104 aligned with the opening 100 in the seal ring 82, and avertical opening 106 ninety degrees displaced from the opening 104. Thesealing means or valve assembly 80 is seated in the annular grooveformed by the annular shoulder 62 in the core member 48 and is rotatabletherein from the pumping position to sealing position in the mannerhereinbelow more fully described.

Seated upon the annular shoulder 66 of the core member 48 and overlyingthe seal ring 82 and its contained rubber seal 84, is a metallic airwasher 108 (Fig. 4) having an inner rectangular recess 110 by which itis keyed to the rectangular projection of the core member 48. At aposition opposite the recess 110, the top of said washer has ahorizontally stepped portion of reduced thickness 112 in the centralportion of which there is provided a vertically apertured,upwardly-extending atomizing nozzle 114. The underside of the washer 108beneath said nozzle is conically recessed, as indicated by the numeral'6, to reduce frictional force with respect to the iiow of fluid throughthe atomizing nozzle. At a position approximately ninety degrees removedfrom the atomizing nozzle 114, the outer edge of the air washer 108 isprovided with an arcuate recess i 118 for the purpose hereinbelowdescribed.

Surrounding the core member 48 and seated upon the air Washer 108 is anannular body member 120, preferably o-f plastic material, having aninterior vertical slot 122 adapted to key said body member on theprojection 71 thereof. The body member 120 is also provided in its outersurface with a vertical guide slot 124 terminating in asidewardly-extending portion of increased Width 126 (see Fig. 6). At aposition approximately ninety degrees removed from the vertical slot 124in the body member 120, the bottom surface is provided with a shallow,inwardly-extending, substantially rectangular recess 128 (see Fig. 7).

An annular metallic purnp cap 130 surmounted by a rubber pump member 132is fittedV upon. the upper end of the core member 48 and rests upon thebody member 120. 4As indicated by the numeral 134 in Fig. 7, thelongitudinal projection 71 of the core member 48 terminates short of theupper end of said core member so 4 that the metallic pump cap is notkeyed to the core member. The parts mounted upon the core member 48 areheld in assembled relation by turning over the upper end of said coremember as indicated at 49.

The pump sleeve 16 reciprocally mounted within the shield 12 ashereinabove mentioned, is hermetically sealed with respect to the cap 18by means of an intermediate gasket 136. The lower end of the pump sleeve16 is inwardly shaped in the form of a lug 138 which in the assembledatomizer is located in the vertical slot 124 of the body member 120,thereby being constrained to vertical motion in said slot, and sidewardmotion only the lower portion of increased width 126 of said slot (seeFig. 2 and Fig. 6). At a position approximately ninety degrees removedfrom the lug 138, the pump sleeve 16 has a substantially semi-circularcutout portion (see Fig. 7), to allow for outward flow of .the atomizedliquid when the atomizer is in pumping condition. v

As can best be seen in Fig. 2, the pump sleeve 16 is held in assembledrelation with respect to the body member 120, by virtue of the fact thatthe pump member 132, after being assembled, blocks they upper end of thevertical guide slot 122.

With respect now to the operation of the improved bottle top atomizerhereinabove described, consideration will rst be given to the instancewhen the device is in open condition or ready for atomizing. Fig. 2show's this condition with pump'sleeve 16 in the upward position, andFig. 7 showsv the sleeve pressed in the downward position. When thepu'r'np sleeve 16 is pressed downwardly, air entrapped in the upporportion of the device will be forced down the passage formed by theflattened portion 68 and out over the horizontally stepped portion ofreduced thickness 112 of the air washer 108. In passing said steppedportion, the air will iiow with increased velocity over the atomizingnozzle 114, whereupon liquid from the bottle B will be drawn up throughthe tube 44, the nipple 42, the channel 38, the bore 58 in core member48, the opening 106 in the rubber seal 82, and the nozzle 114, all ofwhich are in communicative alignment when the device is in operatingposition.

It will be evident that on the downward stroke of the pump sleeve 16,air flow into the bottle is prevented by means of the check valve in theplug member 74. However, upon the return stroke of the pump sleeve 16(in the upward direction). air can pass through the bore 32, channel 40,bore 56, aligned openings 104 and 100 in the rubber seal 84 and theseal` ring 82, respectively, side opening 70 and vertical opening 76,past the check valve ap 78 and into the upper portion of the pump sleeve16. It is further to be noted that this air passage for the returnstroke is of such size as will offer less resistance to air passage thanthe above-described path past the nozzle 114, so that the possibility ofliquid being aspirated inwardly during the return stroke will beminimized.

When it is desired to close the bottle top atomizer, it is onlynecessary to turn the pump sleeve 16 slightly when inv the downwardposition so that its bottom lug 138 becomes latched in thesidewardly-extending portion 126 of the guide slot 124 (see Fig. 8). Inturning the lug 138, extending through the arcuate recess 118 in the airwasher 108, carries with it the seal ring 82 together ,with its rubberseal 84, since the lug 138 will also extend when in this lowermostposition, into the rectangular slot 102 in said seal ring. The resultingrotary movement of the rubber seal 84, will therefore seal off at theannular shoulder 62 of the body member 48, the above- -describedpassages communicating with the vertical bores 30 and 32 leading to theinterior of the bottle B. The 'semi-circular cut-out 140 in the pumpsleeve 16 moreover, will be moved out of alignment with respect to theopening 14 in the outer shield 12 to close olf the chamber surroundingthe nozzle 114 from the outside.

The modification of the invention shown in Fig. 12, diiers only fromthat described above in connection with Figs. 1 through ll, in that thebottle adaptor 142 has an externally threaded portion 144, upon which acylindrical container 146, enclosing the small bottle 14S is screwed.There is thus provided a small, neat atomizing device suitable forcarrying in a pocket or handbag.

Figs. 13 through 17 illustrate an alternative embodiment of theinvention, wherein a modilied form of seal ring is used. In Fig. 18, theseal ring 150, shown in upside down position for clarity of detail,comprises an annular metallic ring having an outwardly-struck pair oflugs 152, 154 comprising at portions 156, 158 spaced from and parallelwith respect to the Ibody of the seal ring and outwardlyextendingportions 160, 162 bent at right angles to said flat portions. Asubstantially square hole 164 is provided in the seal ring 150 betweenthe lugs 152, 154. An arcuate rubber seal 166 (Fig. 17) has a central,substantially square projection 16S adapted to tit into the square hole164 in the seal ring 150 when the end portions of the seal 166 areseated against the lugs 152, 154 (see Fig. 14). A vertical opening 170extends through the seal 166 centrally of its square projection 168. Theends of the seal 166 extend just short of ninety circular degrees fromthe central opening 170. Another lug 172 is struck from the seal ring150 at a position substantially opposite the square hole 164, said lughaving a portion 174 bent parallel to the body of the seal ring at suchspacing thereupon as to be substantially in a plane with the outersurface of the rubber seal 166 when in place. At a positionapproximately midway between the square hole 164 and the lug 172 in theseal ring 150, said ring is provided with a substantially rectangularrecess 176 adapted to receive the lug 138 in the pump sleeve 16 to turnthe ring together with its rubber seal 166 when the device is turned tolocking position as described above in connection with` the tirstembodiment of the invention illustrated in Figs. 1 through ll. Operation'of the modifier device is the same as described in co-nnection with theembodiment illustrated in Figs. l through l2. It is to be noted in thisconnection that the length of the seal 166 is such that it will seal ottthe vertical bore 56 in the core member 48 when the device is in lockedcondition.

While there has lbeen disclosed in this speciication three forms inwhich the invention may be embodied in practise, it is to be understoodthat these forms are shown for the purpose of illustration only, andthat the invention is not to be limited to other specific dis-closure,but may be modied and embodied in various forms without departing fromits spirit. In short, the invention contains all the modifications andembodiments coming within the scope of the following claims.
